First off GF OPs are horrible. Que times, people not knowing what to do, undergeared people, people queing for wrong role, the list goes on. Only time I ever que for GF OPs is if its mostly a guild run and we are doing it coms.

I feel your frustration with not getting replies from folks shouting in fleet. Nothing grinds my gears more than replying to them, not getting a response, and then seeing them shouting again. Not much you can do about this. Some groups are elitest/snobs when is comes to certain roles/jobs.
